For example, if you have bit rates 200, 300, 700, and 1200, and you want to
include only bit rates 200, 700, and the lowest audio rate, your URL would be as follows:

uri/master.m3u8?b=200,700

This produces only the 200 and 700 bit rate streams and the lowest audio bit
rate.

Designate a bit rate range (in kbps) outside of
which the stream or streams you wish to filter fall. The string format is:

b=lower_end-upper_end

For example, if you have bit rates 200, 300, 700, and 1200, and you want to
include all bit rates at or greater than 200 and at or less than 700, your URL format is:

uri/master.m3u8?b=200-700

This produces the 200, 300, and 700 bit rate streams.

Designate the low end of a bit rate range (in
kbps) where all bit rates below the value are filtered. The string format is:

b=low_end-

For example, if you have bit rates 200, 300, 700, and 1200, and you want to
include all bit rates at and higher than 300 kbps, your URL format is:

uri/master.m3u8?b=300-

This produces the 300, 700, and 1200 bit rate streams.

Designate the high end of a bit rate range (in
kbps) where all bit rates at and above the designation are filtered. The string format is:

b=0-high_end

For example, if you have bit rates 200, 300, 700, and 1200, and you want to
include all bit rates lower than or equal to 700 kbps, your URL format is:

uri/master.m3u8?b=0-700

This produces the 200, 300, and 700 bit rate streams.

Any combination of the above.

For
example, if you have bit rates 200, 300, 700, 1200, and 1800, and you want to include all
bit rates except 700, your URL format is:

uri/master.m3u8?b=0-300,1200-

This produces only the 200, 300, 1200, and 1800 bit rate streams and the
lowest audio bit rate.

Note:

If Bit Rate Filtering and the Extracted Audio-Only features are
simultaneously enabled, bit rate filtering is applied first, then audio-only extraction
is applied to the remaining bit rates.

After you specify the set-akamai-hls-revision query
string to 4 or higher
version (as described in Section HLS delivery improvements per HLS spec upgrade), you do not need to set up the Bit Rate Filtering query string. The quality of your
streaming will be automatically corrected.
